SP746-X

1 Form A

Solid State Relay

The SP746-X is a bi-directional, single-pole, single-throw, normally open multipurpose relay. The circuit is composed of one LED on the

input side which activates an optically coupled IC on the output - controlling the firing angle of two back-to-back SCRs. This circuit

assures no false triggering under most adverse conditions, and a tight zero-volt window not exceeding 5V. A 300-ohm input resistor in

series with the LED is also provided in this circuit.
